Rootrainer seedstarters have grooved cells that promote downward root growth and discourage spiraling, yielding deep-rooted seedlings that
transplant easily and adapt quickly to the garden. Cells are 1-1⁄2" square at the top, and they hinge so you can monitor root growth and remove plants
without disturbing roots. Made from plastic; may be reused. The Compact Rootrainer has 20 cells and includes a tray with drainage holes and a clear greenhouse
cover.
